IMPROVEMENT IN .UR|NALS.

Specication forming part of Letters Patent N o. 107, ISS, dated September G, 1870.

To all whom it may concern:

Be it known that l, SAMUEL MALEs, of Cincinnati, Hamilton county, State of Ohio, have invented cert-ain new and useful Improvements in Bowls or Sinks andGonnections for Urinals, Kitchen-Sinks, &c.; and I do hereby declare the following to be a sufliciently full, clear, and exact description thereof to enable one skilled in the art to which my invention appertains to make and use it, reference being hadto the accompanying drawings making part of this specification.

My invention consists in a peculiar construction of the bowl or sink casting and attachments by which the discharge-pipe and strainer are simply and conveniently connected in such a way as to be readily detachable; the object of my invention being to provide connecting devices which dispense with the use of screws or other devices liable to rust fast in use, and at the same time atford simple and convenient means of connection or disconnection for the strainer and discharge-pipe of the bowl or sink.

Figure l is a perspective view of the bowlcasting. Fig. 2 represents, in perspective, the part of the discharge-pipe coupling which surrounds and retains in a peculiar manner the end oi' the pipe. Fig. 3 is a vertical section, showing the device for coupling the pipe, and a detached perspective view of the strainer.

The bowl A shown in the drawing is adapted for attaching in a corner, having two sides, a a', at right angles to each other, and a concave projecting bottom and front, a. This bowl, however, may be made of any desirable form, and adapted for attachment to plain straight walls or corners of buildin gs, &c. rlhe bowl A has a downwardly-projecting neck, B, formed uponit, which terminates in a conical tube, l. On the exterior of the neck B spiral lugs b are provided, and on the interior surface of the neck projecting ledges c are formed to support the strainer O, and lugs c to prevent the accidental displacement ot' strainer C. The strainer C is formed with perforations c", recesses c to engage with the lugs c', and side notches 0 large enough to allow the lugs c to pass. The strainer is ot' conical shape on the exterior, and lits snugly into the conical top of the neck B, the exterior surface or rim around it being of suflicient depth to prevent the strainer from tilting when dropped into place. A slight rotary motion of the strainer after it is in place suiiices to pass the vrecess c under the lugs c', and thus lock the strainer in such a way that it cannot be accidentally displaced. To secure it against wilful displacement a piece of thin lead, or other pliable non corrosive material, F, may be passed through the recess c on one side only ot' the strainer, and connect between the lead pipe and bottom oi' the bowl hook fashion. The strainer may be connected or disconnected after the removal of the lead fastening, it' used, by the use of a forked handle or wrench, which engages in two ofthe perforations c. D is a coupling-ring, which is formed with a conical socket, d, and spiral hook-shaped projections d. The projections el' engage over the spiral projections bon the neck B, and the pipe E, being widened out to fit the conical socket d on the outside, and the conical pipe b on the inside, is drawn tightly over the tubular conical end b by the simple partial rotation of the ring D. This ring can be operated byawrench on the hexagon part d.

It will be seen that by reason of the provision of the conical tube b, and conical shape of the interior of the ring l), that the lead pipe is thus forced into a conical shape, which not only permits the coupling to make the joint between pipe E and bowl A tightly, but prevents the ring from being taken oft' the pipe E when the coupling is disconnected.

A great advantage resulting from the -use of my improvement is, that it permits of the bowl or sink being galvanized or enameled inside and out without materially affecting the connections, and thus exposes no part of the bowl or fastenings to the corrosive action of urine or water.

By the old methods ot' connection for the pipe and strainer, (which chiey consishot' bolts which pass entirely through the bowl-casting,

compelling the use of a putty or other gasketjoint,) the fastenings are constantly exposed to oxidation, and become rusted so tightly together that it is impossible to disconnect without the destruction ot' the bolts and other parts, and often the destruction of the bowl or sink itself. These bolt connections moreover are constantly leaking more or less, owing to the presence of holes through the bowL casting.

If deemed desirable, the bowl or sink may be made of Wedgewood or other earthen were; but Where this is used it may be necessary to insert gaskets or strips of' rubber between the rubbingsnrfaees of the connecting devices.

I claim- 1. In the described connection with the bowl or sink A, having lugs or ears c inthe disehargeopening, the strainer C c c" 0 0, constructed and connected substantially in ihe manner and for the purpose'speeied.

2. In combination with the elements of the preceding clause of claim, the booked locking`- strip F, as described, and for thev purpose specified.

In testimony of which invention I hereunto set my hand.
